Re: Maven Ant Demo
Ahh, now I get it. You are running Maven 3. I hadn't tested Ant based plugins in Maven 3 until now, and apparently it doesn't work as it did in Maven 2.

Re: Maven Ant Demo
Hi Those docs are not up-to-date. I have a small Maven plugin written in Ant that works. I'll try to update the docs shortly using that as an example.

Re: Maven Ant Demo

I've built Java and Groovy plugins for Maven before but never an Ant plugin. So its possible that I simply haven't seen this issue. Maybe post your Ant build XML files on pastebin.org or something and send a link back to the ml so someone could look at it? I agree the "has 0 goal" seems to be your problem. The prefix simply allows you to say "mvn hello:hello" rather than typing the full "mvn org.myproject.plugins:hello-plugin:hello" line.

RE: Maven Ant Demo
That appears to be an artifact of some other experiments that I did. I deleted the contents of my .m2\repository\org\myproject\plugins file and ran again.
